User Review: MontBell Men's U.L. Down Inner Jacket
Price Paid: $150 +/-
Great jacket. Perfect for 3 season use. Light weight, compresses down to nothing, and wind proof. Pull it out at night or use it when not moving. I have used it with a light base layer down in the 30's. Also great for adding warmth to your sleeping system if you do not want to pull out the winter sleeping bag yet...
If you are out in wet weather, you may want to consider the fiber fill instead. Typical for down, get it wet and it loses loft.
There are lighter models out there, but not for this price.
